I went through them a long time ago. It’s not the most in-depth resource, but you will learn enough calculus for when you need to actually apply it or even just pass tests. Also learning math on KA is really fun, there’s something they just get right. I’d definitely recommend giving it a try.
If you don’t feel satisfied after going through the courses, you can always pick up a book afterwards to dig deeper.
